Congratulations on your choice.

RIVA ADVANCE HE are condensing high efficiency sealed chamber fan flue gas boilers.

They are fully elec tronically controlled and have electronic ignition.

Thematerialstheyaremadeofandthecontrolsystemstheyareequippedwithgiveyousafety,

a high level of comfort and energy savings to allow you to get the greatest benefit out of

independent heating.

RIVA ADVANCE HE allow a highe r efficiency by r educi ng the flue gas temperature such that

the water vapour formed during the combustion is condensed out.

This allows a gain of useful heat that otherwise would be lost.

Remember that...

n The manual

--- must be read thoroughly, so that you will

be able to use the boiler in a safe and sen-

sible way;

--- must be carefully kept. It may be necess-

ary for reference in the future.

n First lighting up must be carried out by

competent and responsible engineer.

n The manufacturer

--- disclaim all liability for any translations of

the present manual from which incorrect in-

terpretation may occ ur

--- cannot be held responsible for non---ob-

servance of instructio ns co ntained in this

manual or for the co nsequences of any pro-

cedure not specifically described.

Using the boiler...

n Before lighting the boiler you are ad-

vised to have a professionally qualified per-

son check that the installation of the gas

supply

--- is gas ---tight;

--- isofthecorrectgaugefortheflowtothe

boiler;

--- is fitted with all the safety and control de-

vices required by the current Regulations.

n Ensure that

--- the installer has connected the pressure

relief valve outlet to a drain pipe. The manu-

facturers are not responsi ble for damage

caused by opening of the pressure relief

valve and conseque nt escape of water, if not

connected correctl y to the drain.

--- the install er has connected the conden-

sate outlet to a suitable drain pipe.

n On detecting the smell of gas

--- don’t operate any electrical switches, the

telephone or any device that may produce

sparks;

--- open the windows and doors at once to

create a draught of air which will purge the

area;

--- shut off the gas cocks;

--- get the assistance of a qualified person.

n Do not touch the appliance with parts of

thebodythatarewetordampand/orbare

feet.

n Do not block or modify the condensate

outlet and pipework

n In case of structural work or mainten-

ance near the exhaust duct and/or fume ex-

haust devices or their attachments, turn off

the appliance. On completion of the work,

have a professio nall y qualified person check

their efficiency.

n Repairs (under guarantee) must be car-

ried out only by an approved engineer, using

genuine spare parts. Thus do no more t han

switching off the boiler yourself (see the in-

structions) .

n Your boiler allows heating up of water to

a temperature less than boiling point;

--- must be connec ted to a c entral heating

system and/or a hot water supply system,

compatible with its performance and output;

---canbeusedonlyforthosepurposesfor

which it has been specially designed;

--- must not be touched by children or by

those unfamiliar with its operation;

--- must not be exposed to weather condi-

tions.

n During the operation it is quite normal

that the boiler produces a white plume of

condensation vapour from the flue terminal.

This is due to the high efficiency of the ap-

pliance and may be particularly evident with

low out door temperatures.

Boiler installation and commissioning tips

n The installation must be carried out by

a qualified person who will be responsible for

observing the current Regulations.

Installing the boiler...

n Donotforgettoremovethetransitcaps

and plugs from the boiler connections these

are fitted to every boiler.

n Keep the boiler clear of dust during in-

stallation and in particular do not allow any

dust or debris to enter the top o f the boiler

where the flue connection is made. It is rec-

ommended that you put a dust sheet over the

top of the boiler until you are ready to make

the flue connection.

n Because every boiler is fired and tested

live at the factory, a small amount of water re-

mains within the boiler. It is possible for this

water to initial ly cause the pump to seize. It is

therefore recommended that the pump rotor

be manually turned to free its rotation before

turning the boiler on.

n Remember to release the auto air purge

before filling the boiler. See the instructions to

identify the location of this device.

n This boiler allows to control the flow tem-

perature of the central heating system at very

low levels.

In case of underfloor heating system a tem-

perature limiting device (e.g. a safety thermo-

stat) is recommended to stop the boiler in

case that the water temperature exceeds the

design temperature.

n You are strongly advised to flush out the

system both cold and hot in order to remove

system and installation debris.

n It is also sensible to initially fire and com-

mission the boiler before connecting any ex-

ternal control s such as a room thermostat. By

this method if you have a subsequent prob-

lem following the addition of an external con-

trol you can eliminate the boiler from your

fault analysis.

n If the boiler is fitted with a digital pro-

grammer, when setting the times for auto-

matic operation, remember that for every

“ON” time there must be an “OFF” time to fol-

low and that on every occasion you enter a

time you must also indicate which days that

you want the boiler to follow the timed set-

tings.

n Some products incorporate an anti cycl-

ing time delay. It is normal when first switc h-

ing the boiler on for the boiler to operate on

heating for a few seco nds then switc h off.

After 3--- 4 minutes has elapsed the boiler will

then re ignite and operate perfectly normally.

The ignition delay cycle does not prevent

normal operation of the boiler to provide

d.h.w.

n If you are in any doubts as to the ins talla-

tion or operation of the boiler please read the

instruc ti on manuals tho r oughly and then if

necessary contact Biasi UK for advice and

assistance.

Please remember that if you are in any doubt about the installation of this product you can contact our

Biasi UK Ltd support t he Benchmark initiat-

ive. The Benchmark Log Book is located at

the back of this manual and should be com-

pleted by the Installing/Commissioning E n-

gineer and handed over to the User for fu -

ture reference by other visiting Engineers.

Also included is the Service Interval Record

card that should be completed by the Ser -

vice Engineer following the annual service

maintenance of the boiler and system.

All CORGI Registered Installers carry a

CORGI ID card, and have a registration

number. Both should be recorded in your

Benchmark Log Book. You can check your

installer is registered by calling CORGI di-

rect on 01256 372300.

In order to guarantee safety and correct oper-

ation, it is essential that all the tests are carried

out by a competent and responsible service

engineer before lighting up the boiler.

The tests are described in the installation in-

structions in section 7 c ommissioning.

Ensure that the c.h. circuit is regularly filled with

water (even if the boiler is only used for d.h.w.

supply) checking that the pressure indicated

on the temperature and pressure gauge 4 is

notlowerthanthatshowninFig.2.2.

If the pressure reading on the pressure gauge

is below that shown in Fig. 2.2, then the system

will require topping up. A filling loop is normally

provided by the installer for this purpose.

If you are in any doubt regarding this pro-

cedure you are advised to contact your In-

stalleroranApprovedEngineer.

This appliance is provided with a built in anti---

freeze system that operates the boiler when the

temperature is below 5 ˚C

Therefore, when the boiler is not lit or used in

cold weather, with consequent risk of freezing

do not switch off the boiler at the fused spur

isolationswitchorclosethegasinletcock.

When you do not expect to use the boiler for a

long period and the boiler is not to be used for

frost protection then follow the instructions

given in section 2.6 on page 7.

2.2 Refilling procedure

1 Isolate the boiler from the electrical supply at

the fused spur. Reconnect the f illing loop as

demonstrated i n Fig. 2.1.

Air introduced into the boiler during this filling pro-

cess will vent through the automatic air purger

fitted to the boiler. You may also find it necessary

to vent air from your radiator circuit using your

radiator key, however be aware that excessive

venting will cause the pressure in the system to

drop.

Always ensure that the p ressure gauge is set at the

required pressure.

2.3 Ignition

1 Check that the valves located in the lower part

of the boiler are open (Fig. 2.3).

2.4 C.h. circuit temperature

The output temperature of c.h. water is adjustable

from a minimum of about 25°C to a maximum of

about 85°C (Fig. 2.6), by turning the knob (8).

Adj ustment of the boiler temperature alters the

gas flow at the burner according to the thermal de-

mand in the system. So it is usual to see the burner

litattheminimumlevelformoreorlesslong

periods.

It is possible to fit to this boiler an optional outside

temperature sensor which helps to manage and

control the boiler and system efficiency. The fol-

lowing instructions indicate how to set the output

temperature of the c.h. water depending on

whether the optional outside sensor h as been

fitted.

Minimum

Maximum

Fig. 2.6

Adjustment WITHOUT the external tempera-

ture probe (optional) fitted

In order to achieve optimal settings for economy

and comfort, we recommend adjusting the oper-

ating temperature of the c.h. water according to

the outside temperature, positioning the knob as

follows:

USE

Instructions for use

--- 5 ˚C

From5to15˚C

Between

--- 5 a n d + 5 ˚ C

Fig. 2.7

Your qualified installer will be able to recommend

the most suitable adjustment for your system.

The temperature and pressure gauge (4, Fig. 1.3

on page 2) will allow you to check that the set tem-

perature is obtained.

Adjustment WITH the external temperature

probe (optional)

When the boiler is connected to the external tem-

perature probe (optional), the temperature of the

c.h. flow is automatically adjusted with reference

to the external temperature.

Inthiscasetheboilermustbeproperlysetbythe

installer (as described in section 7.9 of this man-

ual) and the c.h. flow temperature control knob

must be positioned as illustrated in Fig. 2.8.

To satisfy temporary changes or different room

temperatures, the c.h. water temperature can also

be manually increased or decreased within a

range of ±15 ˚C by turning the knob 8 (Fig . 2.8).

More details are given in section 7.9 of this man-

ual.

2.5 D.h.w. temperature

The temperature of the d.h.w. leaving the boiler

can be varied from a minimum of about 35°Ctoa

maximum of about 55°C (Fig. 2.9), by turning the

temperature control knob 9.

Minimum

Maximum

Fig. 2.9

Adjustment of the d.h.w. temperature is complete-

ly separate from that of the c.h. circuit.

The adjustment system integrated within the

boiler automatically controls the flow of gas to the

burner in order to keep the temperature of d.h.w.

delivered constant, between the limits of maxi-

mum and minimum output.

Where the d emand is at a low level or with the tem-

perature set to the minimum, it is normal to see a

cycle of lighting and exting uishing of the burner

when running.

Adjustment

It is advisable to adjust the d.h.w. temperature to

a level commensurate with the demand, minimis-

ing the need to mix with cold water. In this way, the

automatic control facilities will b e fully exploited.

Where lime scale is present in the water supply

(hard water areas) it is also advisable not to ex-

ceed the setting position of the d.h.w. temperature

control knob (9) as indicated in Fig. 2.10. This will

help to minimise the incidences of scale deposits

clogging the domestic hot water heat exchanger

of the boiler.

USE

Instructions for use

Fig. 2.10

In these cases, however, it is advisable to install a

small water treatment device or softener. With

such a device you should avoid periodic descal-

ing.

Consequently, the d.h.w. heat exchanger will keep

its performance consistent for a longer period of

time with resulting gas savings.

If the demand for d.h.w. is so great as to p revent

reaching a high enough temperature,have the ap-

propriate output limitin g valve installed by your in-

staller or an Authorised Service Engineer.

2.6 Extinguishing

To turn the boiler off set the function selector 8 to

the position shown in Fig. 2.11.

The appliance operation light 10 will flash every 4

seconds.

810

Fig. 2.11

When you do not expect to use the boiler for a long

period:

1 Switch off the electricity supply to the boiler, by

means of the fused spur isolation switch;

2 Shut off the g as supply cock 14 and the valves

3.1 Central heating

For reasonably economical service install a room

thermostat.

Never shut off the radiator in the area where the

room thermostat is installed.

If a radiator (or a convector) does not heat up,

check that no a ir is present in it and that its valve

is open.

If the ambient temperature is too high, do not alter

the radiator valves. Reduce the central heating

temperature instead by means of the room ther-

mostat and the function selector (8 in Fig. 3.1).

This appliance is provided with a built in anti---

freeze system that operates the boiler when the

temperature is below 5 ˚C

Therefore, when the boiler is not lit and used in

cold weather, with consequent risk of freezing do

not switch off the boiler at the fused spur isola-

tion switch or close the gas inlet cock.

3.3 P eriodic maintenance

For efficient and continuous operation of the

boiler, it is advisable to arrange maintenance and

cleaning by an Authorised Service C entre En-

gineer, at least once a y ear.

During the service, the most important compo-

nents of the boiler will be inspected and cleaned.

This service can be part of a maintenance con-

tract.

In particular, you are advised to have the following

checks carried out:

--- domestic hot water heat exchanger;

--- condensing heat exchanger

--- burner;

--- exhaust fume duct and flue;

--- pressurisation of the expansion tank;

--- filling up of the central heating circuit;

--- bleeding of air from the central heating system;

--- general check of the appliance’s operation.

3.4 External cleaning

Before carrying out any cleaning, disconnect the

appliance from the electrical mains, using the

fused spur isolation switch fitted adjacent to the

appliance.

To clean the external panels, use a cloth soaked in

soapy water. Do not use solvents, abrasive powd-

ers or sponges.

Do not carry out cleaning of the appliance and/or

its parts with readily flammable substances (for

example petrol, alcohols, n ap htha, etc.).

3.5 Operatio nal faults

If the lock---out signal lamp (6 in Fig. 3.2) comes

this indicates that the safety lock--- out has stopped

the boiler.

To re--- start the boiler, it is necessary to press the

boiler reset button 7 (F ig. 3.2).

Fig. 3.2

F or the first lighting up and following maintenance

procedures for the gas supp ly, it may be necess-

ary to rep eat the resetting operation several times

so as to remove the air present in the pipework.

After five consecutive resetting attempts the reset

button is inhibited. To restore its function it is

necessary to switch the boiler off and on from the

electrical mains, using the fused spur isolation

switch fitted adjacent to the appliance.

Safety lock--- out may occur even in case of an

blockage of the condensate drainage (e.g.

plugged drain pipe).

Itisadvisabletocheckthecondensatedrainage

pipe and traps for cleanness.

In this case and in case of persistent lock--- out call

a competent and resp onsible service engineer.

USE

Useful advice

If noises due to a ir bubbles are heard during

operation...

you should check that the pressure on the tem-

perature and pressure gaug e (Fig. 2.2 on pag e 4)

is not below the correct setting.

If required, top up the system correctly, as de-

scribed in the section 2.2 of this manual.

Bleed any air present in the radiators, if necessary.

If the pressure on the temperature and pres-

suregauge(4onpage2)hasgonedown...

it is necessary to top up the appliance with water

again, so as to raise the pressure to an adequate

level as d escribed in the section 2.2 of this manual.

If topping up with water has to be done very fre-

quently, have the system checked for leaks.

If water comes out of the pressure relief valve

Check on the temperature and pressure gauge (4

on page 2) that the pressure in the central heating

circuit is not close to 3 bars. In this case, tempera-

ture rise in the circuit can cause the pressure relief

valve to open.

So that this does not happen and to d ecrease the

pressure to a normal value, it is advisable to v ent

some of the water in the appliance through the

bleed valves present in the radiators.

If in time, a reduction in domestic hot water

supply is observed...

The likely causes may be impurities caught in the

domestic hot water flow switch filter or limescale

deposited in the domestic hot water heat ex-

changer. It is advisable to have the appliance

cleaned out by an Au thorised Service Centre En-

gineer.

If water should occasionally leak from the

boiler...

shut off the valves positioned under the b oiler

(Fig. 2.12 on page 7) and call an Authorised Ser-

vice Centre Eng ineer.

In this case or in case of problems other than

those mentioned here, switch off the boiler, a s

described in section 2.6 on page 7 and call a

competent and responsible service engineer.
